In this paper, the authors present a protocol ALBA-R that uses converge-casting for wireless sensor networks. ALBA-R is a cross-layer integration of geographic routing and loads balancing, along with a mechanism for detecting and routing around connectivity holes (rainbow). This mechanism together solves the problem of routing around dead ends without overhead-intensive techniques. This protocol efficiently adapts to varying traffic and node deployments, as it is localized and distributed. ALBA-R outperforms other protocols dealing with connectivity holes, especially in low-density networks and critical traffic conditions through extensive NS2-based simulations.
